UK state pensions are a joke, meaning most pensioners with nothing else to fall back on are in a bit of a mess.
Have a piece of advice (if you haven't done it already); look at a variety of places all over Europe and the rest of the world, but check your pension payments won't be reduced if you live abroad.
Whilst I'm not suggesting Indonesia as a likely place, I can use it as an example.
A quid is around 18,000 rupiah, and that easily buys lunch.
The majority of the population live for a month on less than you get each week.
As I suggested, Indonesia would probably be a massive step, but other places could offer the same sort of added value to your pension, but with less of a culture shock and more English speaking people.
